Information about the product including what the product is used for, dosage, warnings, proper use and side effects. This summary will not tell you everything about the product. Contact your healthcare professional if you have any questions about the product.
What the medication is used for
CONTINGENCY ONETM is an emergency or backup
contraceptive.
CONTINGENCY ONETM can prevent pregnancy after a
contraceptive accident (such as a broken condom) or when
no form of birth control was used. Treatment is most
effective if used in the first 72 hours (3 days) following
unprotected sex.
CONTINGENCY ONETM cannot terminate an existing
pregnancy. Although there is no scientific evidence that
CONTINGENCY ONE would harm a developing embryo,
women who are already pregnant should not use this
product.
CONTINGENCY ONETM should not be used in place
of regular contraception. It does not work as well as most
other contraceptives used correctly.
What it does
CONTINGENCY ONETM acts as an emergency
contraceptive by preventing the release of an egg from the
ovary, or preventing sperm and egg from uniting. In
addition, CONTINGENCY ONETM may prevent the
fertilized egg from attaching to the wall of the uterus.
CONTINGENCY ONETM is not effective once a
pregnancy has started, that is once the fertilized egg has
attached to the wall of the uterus. CONTINGENCY
ONETM does not cause an abortion.
CONTINGENCY ONETM can be used following any
unprotected act of sexual intercourse, including:
- When no contraceptive has been used
- When a contraceptive method may have failed, including:
- Condom rupture, slippage, or misuse
- Diaphragm or cap dislodgment, breakage or early removal
- Failure to withdraw before ejaculation
- Miscalculation of the fertile period by women practising periodic abstinence
- IUD expulsion
- Missed oral contraceptives
- A delay in starting a new packet of oral contraceptives
- A delay in getting a scheduled contraceptive injection
- In cases of sexual assault (rape)
When it should not be used
Do not use CONTINGENCY ONETM if:
- you have a confirmed or suspected pregnancy
- you are allergic to Levonorgestrel, or to any ingredient in the formulation (see list of nonmedicinal ingredients below)
- you have abnormal vaginal bleeding
What the medicinal ingredient is

What the non-medicinal ingredients are
Colloidal silicon dioxide, corn starch, lactose monohydrate, magnesium stearate and polyvinyl pyrrolidone K-25.

Warnings and precautions
Serious Warnings and Precautions
- CONTINGENCY ONETM provides no protection against HIV/AIDS and other sexually transmitted diseases (STDs), such as syphilis, gonorrhoea, chlamydia, and herpes. If you are worried about whether you may have been infected with HIV/AIDS, or other sexually transmitted diseases, talk to your health professional about your concerns and ask how you can protect yourself in the future.
- If your period is delayed more than 1 week, you should contact your doctor and have a pregnancy test done.
CONTINGENCY ONETM is for Emergency
Contraceptive Use Only and should not be used on a
regular basis. CONTINGENCY ONETM is not as
effective in preventing pregnancy as most other birth
control methods (e.g. oral contraceptive pills, IUDs,
implants or condoms, etc.). It should not be relied on
for routine birth control by sexually active women.
CONTINGENCY ONETM provides only short-term
protection against pregnancy. Sexual activity that takes
place later can still result in pregnancy if no contraceptive
is used. You must abstain from sex or use another barrier
method of birth control until your next normal period to
make sure you do not get pregnant.
In all women, emergency contraception should be taken as
soon as possible after unprotected intercourse. There is
some data that levonorgestrel may be less effective with
increasing body weight or body mass index (BMI), but
these data were limited and inconclusive. If you have any
questions regarding this, please consult with a health care
professional.
BEFORE you use CONTINGENCY ONETM, talk to your
doctor or pharmacist if you have now or have previously
had any of the following conditions:
- Unusual vaginal bleeding that has not yet been diagnosed
- Known or suspected breast cancer
- Active liver disease or tumour
- You have diabetes
- You have high blood pressure
- You are pregnant or breast feeding
Interactions with this medication
Before you use CONTINGENCY ONETM, talk to your
doctor or pharmacist if you are taking any of the following

- antibiotics (ampicillin, cotrimoxazole, tetracycline, temafloxacin, clarithromycin)
- rifampicin
- rifabutin
- griseofulvin
- Hypericum perforatum (St. John’s wort)
- ulipristal acetate
If your period is delayed more than 1 week and you were

Proper use of this medication
Usual Dose
CONTINGENCY ONETM can prevent pregnancy if the
tablet is taken within 72 hours (3 days) and preferably
within 12 hours after a contraceptive accident or
unprotected sex (sex without birth control). Do not
delay starting treatment. CONTINGENCY ONETM is more
effective the sooner you start after unprotected intercourse.
CONTINGENCY ONETM can be taken with a glass of
water.
If you vomit within 2 hours of taking CONTINGENCY
ONETM, call your doctor or pharmacist as you might need
another dose.
Important: If more than 72 hours (3 days) have passed
since unprotected sex occurred, CONTINGENCY ONETM
may not be effective. See your health professional as soon
as possible to discuss other options.
Although the risk of pregnancy is highest in the middle of
the menstrual cycle (possibly as early as day 10 after the
beginning of your last period), pregnancy can occur at
other times during the menstrual cycle. CONTINGENCY
ONETM can be administered anytime during your monthly
cycle if you are worried about an unwanted pregnancy.
The treatment does not bring on menstruation. You may
experience spotting a few days after taking
CONTINGENCY ONETM, but this is not a period. Your
next menstrual period should come on time (or a few days
early or late). If your period is delayed more than a week
or if you have any other cause for concern, talk to a health
professional. More than occasional use (more than once in
a menstrual cycle or more than once a month) may upset
your menstrual cycle (period).
If you are sexually active and do not wish to become
pregnant, you should use a reliable method of
contraception on a regular basis. If you want more
information about regular contraceptives or if you are
having trouble using a method, ask your health
professional for help in choosing a method that works for
you.
Overdose
Symptoms of overdose may include nausea, vomiting, vaginal bleeding, and may lead to menstrual cycle disturbances.
Side effects and what to do about them
CONTINGENCY ONETM can cause temporary side effects in some women. These side effects generally do not last more than 24 hours. Common side effects include:

lower abdominal pain, painful menstruation and vaginal
